Throughout this manual, notes, cautions, and warnings are used to
highlight important information. These highlights are categorized as
follows:
NOTE
An operation, procedure, or background information
which requires additional emphasis or is helpful in ef-
ficient operation of the system.
CAUTION
A procedure which, if not properly followed, may cause
damage to the equipment.
!
WARNING
A procedure which, if not properly followed, may cause
injury to the operator or others in the operating area.
WARNING
Gives information regarding possible electrical shock
injury. Warnings will be enclosed in a box such as this.
1.02 Important Safety Precautions
!
WARNING
OPERATION AND MAINTENANCE OF PLASMA ARC
EQUIPMENT CAN BE DANGEROUS AND HAZARDOUS
TO YOUR HEALTH.
Plasma arc cutting produces intense electric and
magnetic emissions that may interfere with the proper
function of cardiac pacemakers, hearing aids, or other
electronic health equipment. Persons who work near
plasma arc cutting applications should consult their
medical health professional and the manufacturer of
the health equipment to determine whether a hazard
exists.
To prevent possible injury, read, understand and follow
all warnings, safety precautions and instructions before
using the equipment. Call your local distributor if you
have any questions.
GASES AND FUMES
Gases and fumes produced during the plasma cutting process can be
dangerous and hazardous to your health.
• Keepallfumesandgasesfromthebreathingarea.Keepyour
head out of the welding fume plume.
• Useanair-suppliedrespiratorifventilationisnotadequateto
remove all fumes and gases.
• Thekindsoffumesandgasesfromtheplasmaarcdependon
the kind of metal being used, coatings on the metal, and the
different processes. You must be very careful when cutting
or welding any metals which may contain one or more of the
following:
Antimony Chromium Mercury
Arsenic Cobalt Nickel
Barium Copper Selenium
Beryllium Lead Silver
Cadmium Manganese Vanadium
• AlwaysreadtheMaterialSafetyDataSheets(MSDS)thatshould
be supplied with the material you are using. These MSDSs
will give you the information regarding the kind and amount of
fumes and gases that may be dangerous to your health.
• Forinformationonhowtotestforfumesandgasesinyour
workplace, refer to item 1 in Subsection 1.03, Publications in
this manual.
• Usespecialequipment,suchaswaterordowndraftcutting
tables, to capture fumes and gases.
• Donotusetheplasmatorchinanareawherecombustibleor
explosive gases or materials are located.
• Phosgene,atoxicgas,isgeneratedfromthevaporsofchlo-
rinated solvents and cleansers. Remove all sources of these
vapors.
• Thisproduct,when usedforweldingorcutting,produces
fumes or gases which contain chemicals known to the State
of California to cause birth defects and, in some cases, cancer.
(CaliforniaHealth&SafetyCodeSec.25249.5etseq.)
ELECTRIC SHOCK
Electric Shock can injure or kill. The plasma arc process uses and
produces high voltage electrical energy. This electric energy can cause
severe or fatal shock to the operator or others in the workplace.
• Nevertouchanypartsthatareelectrically“live”or“hot.”
• Weardryglovesandclothing.Insulateyourselffromthework
piece or other parts of the welding circuit.
• Repairorreplaceallwornordamagedparts.
• Extracaremustbetakenwhentheworkplaceismoistor
damp.
• InstallandmaintainequipmentaccordingtoNECcode,refer
to item 9 in Subsection 1.03, Publications.
• Disconnectpowersourcebeforeperforminganyserviceor
repairs.
• ReadandfollowalltheinstructionsintheOperatingManual.
FIRE AND EXPLOSION
Fireandexplosioncanbecausedbyhotslag,sparks,ortheplasma
arc.
• Besurethereisnocombustibleorammablematerialinthe
workplace. Any material that cannot be removed must be
protected.

• Ventilateallammableorexplosivevaporsfromtheworkplace.
• Donotcutorweldoncontainersthatmayhaveheldcombus-
tibles.
• Providearewatchwhenworkinginanareawhererehazards
may exist.
• Hydrogengasmaybeformedandtrappedunderaluminum
workpieces when they are cut underwater or while using a water
table. DO NOT cut aluminum alloys underwater or on a water
table unless the hydrogen gas can be eliminated or dissipated.
Trapped hydrogen gas that is ignited will cause an explosion.
NOISE
Noise can cause permanent hearing loss. Plasma arc processes can
cause noise levels to exceed safe limits. You must protect your ears
from loud noise to prevent permanent loss of hearing.
• Toprotectyourhearingfromloudnoise,wearprotectiveear
plugs and/or ear muffs. Protect others in the workplace.
• Noiselevelsshouldbemeasuredtobesurethedecibels(sound)
do not exceed safe levels.
• Forinformationonhowtotestfornoise,seeitem1inSubsec-
tion 1.03, Publications, in this manual.
PLASMA ARC RAYS
Plasma Arc Rays can injure your eyes and burn your skin. The plasma
arc process produces very bright ultra violet and infra red light. These
arc rays will damage your eyes and burn your skin if you are not
properly protected.
• Toprotectyoureyes,alwayswearaweldinghelmetorshield.
Also always wear safety glasses with side shields, goggles or
other protective eye wear.
• Wearweldingglovesandsuitableclothingtoprotectyourskin
from the arc rays and sparks.
• Keephelmetandsafetyglassesingoodcondition.Replace
lenses when cracked, chipped or dirty.
• Protectothersintheworkareafromthearcrays.Useprotective
booths, screens or shields.
• UsetheshadeoflensassuggestedinthefollowingperANSI/
ASC Z49.1:
Minimum Protective Suggested
Arc Current Shade No. Shade No.
Less Than 300* 8 9
300 - 400* 9 12
400 - 800* 10 14
* These values apply where the actual arc is clearly seen.
Experience has shown that lighter filters may be used
when the arc is hidden by the workpiece.
LEAD WARNING
This product contains chemicals, including lead, or otherwise produces
chemicals known to the State of California to cause cancer, birth defects
and other reproductive harm. Wash hands after handling. (California

1.05 Precautions De Securite Importantes
!
AVERTISSEMENTS
L’OPÉRATION ET LA MAINTENANCE DU MATÉRIEL DE
SOUDAGE À L’ARC AU JET DE PLASMA PEUVENT PRÉ-
SENTER DES RISQUES ET DES DANGERS DE SANTÉ.
Coupant à l’arc au jet de plasma produit de l’énergie
électrique haute tension et des émissions magnétique qui
peuvent interférer la fonction propre d’un “pacemaker”
cardiaque, les appareils auditif, ou autre matériel de santé
electronique. Ceux qui travail près d’une application à
l’arc au jet de plasma devrait consulter leur membre
professionel de médication et le manufacturier de matériel
de santé pour déterminer s’il existe des risques de santé.
Il faut communiquer aux opérateurs et au personnel TOUS
les dangers possibles. Afin d’éviter les blessures possi-
bles, lisez, comprenez et suivez tous les avertissements,
toutes les précautions de sécurité et toutes les consignes
avant d’utiliser le matériel. Composez le ou votre distri-
buteur local si vous avez des questions.
